Be it known that Fnnnnnron MiLHAHN, a citizen of thev United States, fresiding at Dwight, in the county of Livingston and State of illinois, have invented certain new and useful improvements in Stirring Devices for Caldrons, of which the following is a specication, reference being had therein to the accompanying drawings.

This invention relates to caldrons and has for an object to provide a means for stirring the contents of a caldron at a distance removed from the caldron itself, whereby the operator is protected from the heat and discomfort of close proximity to the caldron.

A further object of the invention is to provide, in combination with a caldron, an agitator adapted to'rotate within the caldron and scrape the sides thereof, with operating means extending from the ealdron to a point of comfort, with means at such point for operating the agitator. y

With these and other objects in view the invention comprises certain novel parts, units, elements, combination and functions as dis-V closed in the drawings together with mechanical equivalents thereof as will be hereinafter more fully described and'claimed.

1n the drawings:

Figure 1 is a view in side elevation of a conventional caldron with the agitator ap-V plied thereto;

Fig. 2 is a top plan view of such caldron and agitating means;

Fig. 3 is a transverse or diametrical sectional view through the caldron showing the agitating operating means in section;

Fig. 4 is a detail fragmentary sectional view showing the means of attaching the device to a caldron;

Fig. 5 is a view in elevation of the shaft journaling' support, and

Fig. 6 is a detail perspective view of a. fragment of the agitator.

Like characters of reference indicate corresponding parts throughout the several views. v

r1`he device of the present invention is adapted for and intended to be used with caldrons of various styles, shapes and sizes,

as indicated conventionally at 10. Conven-V tional caldrons are ordinarily provided with ears 11 diametrically disposed and the pres-:

ent device comprises a spider 13 having means, as the hooks 12, for engaging the speeiaeanwf Lederwaren. waage/Reed Dec. 2, 192i. ieai. seriaino. sacas ears of suchfcaldrom said'hooks-extending through-slots 14 in the spider and'provided with winged nuts 15 for'attaching the device to the caldron. Y

The spider 13 serves as a bearing to journal the shaft 16 which extends upwardly above the spider and is provided with a gear 17 secured thereto.

Upon the spider is also mounted a bearing-box 18 journaling a shaft 19 which carries a pinion k20 intergeared with the gear 17. Y

The shaft 19, or an extension thereof, 21, is provided with a crank'QQ by which the pinion 20, the gear 17 and shaft 16 are r0- tated. The shaft 19, or 21 extended, is journaled in the bearing 23 supported by an adhoop providingfor the Vcurvature of the hoop 30 to conform to the curvature of the interior of the caldron, so that as said hoop rotates under1` the action of the rotating shaft 16 it will scrape the interior of the caldron,

agitating the contents and clearing the sides from adherents. The adjustment of the hoop 30 relative to the cross-head 29 may be accomplished in the ordinary manner by having the cross-head provided with vperforations 31 and the hoop with perforations 32. through which are extended bolts 33.

The caldron is supported in any usual and ordinary manner, as by the tripodV 34, so that a fire may be maintained beneath the caldron' in the usual and ordinary manner of operation. 1t is believed that the utility and operation of the device will be perfectly vapparent from the foregoing description and insecured a bendable hoop 30, the adjustment and the iiexibility of the spection of drawings and that further dei yielding material adapted to conform and lio bold itself in direct Contact with a containei having a curi/storm bottom, and means to vary the circumferential extent of tbe scraper to adapt it to bottoms of diifi'eient iadii.

I2j. The combination with s rigid cont-aineil having a cuivziorm bottom, of ey soaper comprising a hoop of yielding material adapted to conform itself to and move in direct Contact with the bottom, and means to rotate the scmpei'.

3. The combination with a rigid container incisos having a curvafoim bottom, ot a scraper compiising a hoop of yielding material adapted to conform itself to and move in 15 direct Contact with the bottoni7 means to Vary the ciicumferential extent ot" the hoop, and means to iotate the scraper.
